The feature-rich, USA-made Grouse is made for comfort in all conditions. GORE-TEX lining provides breathable, waterproof protection and the full-grain leather and Cordura upper combined with Danner's famous stitchdown construction gives rugged durability and a wide platform for stability. The Danner Bob outsole, known as one of the world's best hunting outsoles, tracks steadily in the snow and mud while continuously self-cleaning.
